The vinyl is called Ambla and to be truthful although it was supposed to be a cheap alternative to leather fitted by Jaguar to save some money, (leather was an option but cost more) if you had a leather interior you would be throwing it away now. Judging by the condition of the car it does look as though it has been sat for a time and the leather untreated would have dried up and cracked by now. I have black Ambla in my S type and it still looks new 54 years on.

It took me 18 months (by myself) from purchase to back on the road with my S type but I took it back to bare metal and removed every nut and bolt, everything was cleaned, polished, refurbished and if needed bought new. I think a year to get a good running and driving car is doable but with all these things other things get in the way. Do not set a target date but if you do, say a year then add 9 months as a contingency. Same with the money budget. Either do not set a budget or if you do set a number and then double it plus add another 50% as a contingency. I thought I was done and then found I had to have the gearbox rebuilt as the car was not running when I bought it and I wrongly assumed the gearbox was OK.
Although there are not many 420s on this forum the 420 shared a lot of parts with the Mk2 and the S Type and there is a wealth of knowledge on this forum that you can tap into so don't be afraid of asking questions because we love to answer them. If you want a 420 service manual on a PDF file send me a PM with your e mail and I will send one to you as a present.
